June Solar Generation and Export Numbers
Here is the overview for June 2024. On the 5th June We added three more 3.2 kWh battery taking us to 19.2 kWh of battery storage. This is in preparation for the heat pump installation on the 22nd of June. This allowed us to force discharge the batteries a bit more if the Agile rate was good.
We again not only covered the electricity we imported, but also the standing charge. In fact we were only £3.57 from covering the gas as well.
The worst generation day was the 12th with only 12.80 kWh. The best was the 20th when 32.80 kWh was generated, the highest this year and only 0.1 kWh from our record.
The best export day was the 15th with 22.20 kWh. Some of this was force export from the battery.
Rather than show an export profit, I thought it would be easier to show the cheapest day.
As solar panels output declines over the years I have added the 2023 June generation to the table at the bottom. Of course weather comes into it as well, but I thought it would be interesting to track.
So far this year we have had 68 days where we generated more solar than we consumed, and 100 days more solar was generated than we imported from the grid.

This is the Octopus Watch report comparing other Octopus tariffs. We don’t have an EV, but thought it would be an interesting data point

Octopus Agile
The costs shown here do include the standing charge. Any comparisons are compared to the unit cost if we were not on Octopus Agile, which is 25.255p per kWh. This is the new unit cost after the price cap took affect. The standing charge was 0.4211p
As mentioned above we are still using overnight slots due to my new export strategy. The average slot price was quite high this month.
